TANK FOR WATER-CLOSET VALVES.

To all whom it may concern e Be it known that I, PHILIPHAAS, a citizen of the United States, presiding at Dayton, in the county ofMontgomery and State of Ohio, have invented certain. new and useful Improvements in'Tanks for- WVater- Closet Valves; and I do hereby declare the able others skilled inthe art to which it appertains to make and use the same.

- My invention consists in the novel features hereinafter described reference being following description wing tank open to the atmosphere is employed as a-reservoir forthe flushing water which.

is accumulated after each flushing opera tion, from a supply pipe or main controlled (by .a, valve actuated by Hit rises with the level ofthejvater in the tank, gradually, closes the valve andshuts type-30f; flush apparatus has been devel-' A oped in which this open flush tank is dispensed with and in lieu thereof a closed off the supply. More recently a different air-tight tank isused in which the water accumulates in such manner as to compress i-thelair 1n the 'tank to a pressure equal to i-that of the water in themain with which the tank is connected, so that the water 1s discharged from thetank under this high pressure insteadof, by gravity as in the in- ,SbttlltttlOllS in which the open flush tank is employed, and these closed tanks are .usu-

. ally-constructed of cylindrical form in order towithstand' the highpressure to which they are subjected, usually from sixtyto 1 eighty pounds per square inch.

stalled in buildings formerly equipped with it is necessary to remove the rectangular open tank, whichbyreason of its form is not adapted to be hermetically sealed or to :wi'thstandthe hig pressures. 5 9 9 h re -decoration: thereof.

pressures applied to the rectangular surface of the ordinary style of tank would tend to burst the same or cause them to leak. In many instances the rectangular open tanks have been installed in bath grooms: in private dwellings and in other buildings at considerable expense, and they have been decorated in harmony with the decorations of the room in which they are .locate d, and in some instances the open.

tanks are made of expensive material as porcelain, etc, so that the r elimination would mean not only a considerable loss, hadto the accompanying drawing whichillustrates one embodiment of the iinvention selected by me for'the purpose of illusy -tratingthe same and the said inventionis fully set forth in the vandolaimsr V For many years a type of flushing apparatus has been; in use in connection with Water'closets in which a rectangular flush but would necessitate the entire re-decoration of the room at large expense in order to obliterate all evidences of the previous location of the rectangular tank. This fact has prevented in many instances the installation of the latter type of flushing apparatus where its introduction has been sures to which it may be subjected and to give the required capacityfor holding the necessary amount of water and compressed air, and which at the same time is so constructed that it may be placed within, and

be entirely concealed, by the usual open flush tank already installed, which in such case becomes merelya casing for the airtight tank, thus enabling the installation of the flushing apparatus operating in conjunction with such an airetight tank, in

private houses and other places at present equipped with the open flush tanks, without dispensing with the open flush tank body or affecting in'any way the appearance of the bath 'room or other room in which the apparatus is installed, or requirlng any In the accompanying drawings in which I have illustrated one. form or embodiment of my invention for the purpose of illustrating the same; i Figure 1 represents a sectionalv ew of my improved flush tank placed with n a rectangular openfiush tank from which the usual ball flush and water control valve has been removed. Fig. 2 represents a. top plan view of my improved tank showing the surrounding walls of the rectangular open flush tank in section. I

In carrying out my invention I form my improved air-tight flush tank in a plurality of sections arranged side by side, each section comprising a cylindrical body 1, closed at the top and bottom, preferably by means of pressed sections :2, 3, respectively, which are riveted, brazed, or welded to the cylindrical body 1' in well known ways, so that each section is air-tight. The sections may be made of any suitable metal as sheet iron or steel (which is preferably alvanized), copper, brass, etc., and of sufficient thickness to withstand the pressures to which they are subjected. These sections will be of such a diameter and length that when placed side by side they will easily fit within the standard rectangular flush tanks now in use,

'as indicated in the drawing;

The several sections W1ll be connected in any deslred way so as to place thelr interlor compartments in communication.

This may beaccomplished, for example, by means of nipples H, which may be passed through one where three are employed, is provided" wlthmeans for attachlng a plpe indlcated' reglstering, apertures in adjacent sections,

preferably near the bottom thereof, and secured by riveting, by threaded connection, by soldering, or otherwise, before the adja cent heads are inserted in the process of manufacture. connected by one or more of such nipples as desired, and the several sections of the tank, preferably three in number, will be held firmly together by the nipples and may befurther united by means of soldering or otherwise (as indicated at 9) as desired, in order to form a SOllCl integral tank structure.

One of the sections, preferably the central at 5,:which will be so located so as to conls'oldered' in order to make it air-tight, if

-necessary or desired.

7 represents the ordinary flushing pipe which is connected by a union '8, to the section or nipple 5, for convenience in installing the apparatus.

,"As illustrated in the drawing, my improved tank can be readily inserted in the interior of any standard flush tank, by removing the ball float and valve and'pipe connections, and in the drawing I have shown a porcelain tank at 10 provided with a removable cover 11 of usual or well known construction, to illustrate the application of The adjacent sections may be m improved air-tight tank thereto. Ob viously my improved tank is inserted in the rectangular flush tank so that the short pipe 5 extends through the bottom opening of the flush tank 10 and the usual connection is made by pipe 7 with the flushing valve of well known character, which controls the admission of water to the air-tight tank and the discharge of water from the tank through the pipe 7 to the closet bowl. As

will readily be seen, when the water enters the air-tight tank through the pipefT, it will distribute itself into the several sections of the tank, and as the water level rises the air in the tank sections will be compressed until the air pressure equals and counterba-lances' that of the entering water, as is usual in the case of air-tight flush tanks of thischaracter. When the flushing valve is operated, the compressed air in the upper part of each of the sections will operate equally on the surface of the water to expel it through the pipe 7 to the bowl by way of the flushing valve, in the usual manner;

I do not limit myself to the precise number of sections which I may employ in making the flush tank, nor to the particular details of construction thereof. It is only nec essary that a sufiicient number of sections of a diameter suitable to fit within the narrow width of the open tank, and to afford a sufiicient capacity, are employed. I prefer to employ three sections arranged as shown in the drawing, as this affords a convenient location for the pipe 5 in the center of the lower head of the central section, but in case a larger or smaller number of sections is employed, the pipe connection can be made with one of thesesections' in any usual or desired manner.

By the use of my improved air-tight flush tank, the installation of the same in connec tion with bathrooms and other rooms in private houses and other buildings now equipped with theopen type of flush tank can be readily effected without marring the appearance of the room, without removing the rectangular tank, and without necessitating material repairs or re-decorations.

While Ihave described the sections of my improved'tank as being made of a cylindrical body 1 and compressed heads 2 and 3, secured thereto by riveting, brazing, soldering, or otherwise, it is obvious that these sections may be formed in any desired manner and that one or other of'the heads may i be formed integral with the cylindrical body if desired, or as may be found most convenient and economical in' manufacturing the same.

What I claim and desire to secure by Letfters Patent is f 1. As a new article of manufacture, the herein described air-tight flush'tank comprismg a plurality of sections, cylindrical in cross-section, placed side by side and communicating with each other, whereby the said tank may be placed in and concealed within the ordinary open flush tank.

2. As a new article of manufacture, an air-tight flush tank comprising a plurality of sections, cylindrical in cross-section, arranged side by side and rigidly connected together, said sections communicating with each other, and one of said sections being provided with a water inlet and outlet,

- whereby said tank may be placed in and concealed within the ordinary open flush tank.

3. As a new article of manufacture, an air-tight flush tank comprising a plurality of sections, cylindrical in cross-section, ar ranged side by side, and having their adjacent walls rigidly united, said sections being connected with each other by nipples to afford free communication between the interiors of said sections, and having a water inlet and outlet aperture in one of said sections;

4:. As a new article of manufacture, an airtight flush tank comprising a plurality of sections, cylindrical in cross-section, ar ranged side by side, each section comprising a cylindrical body closed at each end, the adjacent portions of the cylindrical bodies being united, said sections being in communication with each other adjacent to their lower ends, and one of said sections being provided at the bottom with a water inlet and outlet aperture.

In testimony whereof I ailix my si PHILIP ature. AAS.
